WILSON I-I. ALEXANDER, OF PHILADELPHIA, PENNSYLVANIA.

SHIPPING-JACKET.

Z2) Zt efr/wm t may concern.' j

Be it known that I, VILsoN I'I. ALEXAN- DER, a citizen of the United States, and resi-` dent of Philadelphia, in the county of Philadelphia and State of Pennsylvanimhave invented certain new and useful Improvements 1n Shipping-Jackets, of which the following rough handling and which act as non-conductive coverings to keep cool the contents `of the vessels.

It has for its object the provision of a flexible jacket that can be `readily Wrapped about Va vessel and form a comparatively tight closure, and one that can be employed to hold ice upon the top of the vessel for refrigerating purposes.

The invention consists of a `device of the novel construction `hereinafter described, pointed out in the appended claims and illustrated by the accompanying drawings.

In the drawings, in which similar reference characters designate `corresponding parts, .j V

Figure 1 is a vertical sectional view, on the line 1-1 of Fig. 2, of a jacket embody ing the invention, the jacket being shown in position on an ordinary milk-can.

Fig. 2 is a horizontal sectional view on the line 2-.-2 of Fig. 1.

Fig. 3 is a detail view showing the fastening device for one of the holding straps.

Fig. 4 is a perspective view, showing the inner side of a portion of the jacket.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 1.

The main part of the jacket consists of a flexible casing 1 of suitable waterproof material, such as a woven fabric embedded in plastic composition. The dimensions of this casing are such that it can be wrapped about the vessel with considerable overlap at its edges, as at 2, and so as to extend above the `Specieation of Letters Patent.

serve to strengthen the casing, but are spaced l only form non-conductors to the higher temperature outside of the jacket, but also form vertical passages leading down from the icechamber 3 alongside of the vessel into which liows the cold air from the ice-chamber and the cold water from the melted ice to cool the contents of the vessel inclosed by the jacket. The casing is held in place around the vessel by the straps 5 having the usual buckles 6.

In the inner edges of the battens 4 are the notches 7 to engage the rim of the vessel. Ordinarily the engagement of the rim of the vessel with these `notches will hold the jacket fromslipping oifthe vessel. As a further precaution against slipping, hooks 8 are secured to the lower ends of several of the battens to engage the bottom flange of the vessel. j j

To the inner face of the casing 1, between the lower ends of the battens 4, are the blocks sages between the battens to prevent the escape of the cold lair and drip from the bottom of the jacket.

A circular lid 10 fits in the upper end of the casing when the latter is wrapped about a cylindrical vessel to close the ice-chamber. On the under side of this lid is the plate 11 having tongues 12 projecting at intervals from its periphery. Each of thesey tongues will enter the space between two adjacent battens, and when the lid is turned it will engage the recess 13 in the side of one of the battens. With these tongues 12 in engagement with the recesses 13 the lid will be firmly held in place on the jacket. To prevent the accidental turning of the lid and the freeing of the tongues, a pin 14 is pushed through an opening in the lid back of one of thebattens. By removing the pin the lid can be easily turned to free the tongues 12 from the recesses 13 so that the lid can be removed. The lid not only forms a cover for the ice-chamber, but it also acts to strengthen the upper end of the jacket when the latter is-in place.

The jacket is particularly adapted to the protection of cans used in the shipment of milk. Before the milk is poured into the can it is thoroughly chilled. After the can has been filled the jacket is Wrapped about it and secured in place. The jacket not onl protects the can against injury from roug handling, but through insulation serves to preserve the milk in its chilled condition.

` -During cool weather the insulation provided by the jacket would be suiiicient `to preserve the milk in its chilled condition during shipment, but in hot Weather ice could` be `placed inthe chamber above the can. After ,each shipment the jacket should be removed `and the can cleaned for the next shipment.

Owing to yitsi'lexibility andnieans of securing the jacket can be easily removed from the vessel. Owing to the Wide overlap ofl `the meeting-edges of `the jacket the latter Patent is:

1. Ina shipping jacket, a removable ilexible casing of heavy sheet fabric or like ma- `iterial shaped .So-that it can be Wrapped.

sel, vertical battens secured to the inner face of the flexible casing to bear against the Wall of the contained vessel, `said battens being spaced apart to 'oim air-spaces between the casing and the Wall of the contained vessel, and fastening means Jfor temporarily securing the easing around the contained vessel.

2. In a shipping jacket, a flexible casing to be Wrapped around the vessel and to extend above the top of the contained vessel to form i a chamber thereover, vertical battens secured to the inner face of the casing to i bear against the `Wall of the contained vessel, said -`battens being spaced Vapart to form .air-
